BOOK-COVER PROTECTOR.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed October 14, 1919. Serial No. 330,537.

To all whom it may concern:

Be it known that I, ALBERT T. \VALRAVEN, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas', have invented certain new and useful Improvements in Book-Cover Protectors, of which the following is a specification.

This invention relates to new and useful improvements in book cover protectors.

The object of the invention is to provide a superior protector which is adjustable and which may be fastened on a book either with an adhesive or by means-of tongues and slits. A prime object is to provide a protector which when folded will provide reinforcing at the corners thus strengthening and prolonging the life of the protector.

Another feature resides in the provision of guide lines along which the protector may be,

cut to provide the proper flaps and tabs for folding and reinforcing.

In carrying out the invention a protector sheet is out along guide lines so as to prov de the proper flaps, tongues and tabs to receive the book covers and back; these parts forming pockets fpr the book covers. The tabs formed at the corners are folded down onto the outer side of the protector and a tongue provided at each corner which is folded in ward over the end flap receiving the book cover. This gives two thicknesses of the protector material on the inside and outside of the protector at each corner, thereby reinforcing the protector. The tongues may either be glued or inserted in slits in the end fla s.

fhe invention will be more readily understood-from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherem:

Figure 1 is a face. View of the outer or obverse sideof the protector sheet,

Fig. 2 is a face view of the inner or reverse side of the protector sheet,

Fig. 3 is a detail showing the back tongue folded inward,

' Fig. i is a detail showing the inner side of the protector and one of the corner tabs before it is folded down,

Fig. 5 is a similar view showing the inner side of the protector, and the next step in the folding Fig. 6 is a detail showing one of the corner tabs folded down and the tongue ready to be folded inward,

Fig. 7 shows the next step in the folding of the tongue, I

Fig. 8 shows the outer side of the completed corner,

Fig. 9 is a face view of the outer side of the protector showing slits for the tongues,

Figs. 10 and 11 are details showing successive steps in the folding and inserting of the tongue into one of the slits,

Fig. 12 is a face view of the outer sideof a two piece protector, and.

Fig. 13 is a longitudinal sectional view of the same, the flaps being folded inward.

1n the drawings the numeral 10 designates a sheet of heavypaper or other suitable material from which the protector is made. Each corner of the sheet is out off at an angle of about forty-five degrees and adjacent each cut oif corner or beveled edge a plurality of parallel guide lines 11 are printed or impressed on the outer or obverse side ofthe sheet. At the top and bottom of the center of the sheet diverging groups of guide lines 12 are printed or impressed on the sheet.

In fitting the protector to a book the latter, as indicated by dotted lines A is laid on the sheet so that its corners B register with one of the guide lines 11 or is adjacent thereto. The sheet is then cut or slit along these lines, as is indicated in Figs. 1 and 2. The sheet is also cut along the lines of the groups 12 as is indicated in the same figures.

The book is removed and the sheet 10 turned over so that its inner side or face is uppermost as is indicated in Fig. 2. The diverging cuts at the top and bottom in the groups 12 form top and bottom tongues 12 which are folded inward, (Fig. 3). 'The book is now laid on the sheet so that its back rests on the tongues 13 which act to reinforce the back. Top and bottom flaps 14 are provided when the lines 11 and 12 are cut, as are also tabs 15. The flaps 14 are folded inward and down upon. the book covers (Fig. 4). The projecting ends of the sheet form end flaps 16 and these are folded inward and down onto the flaps 14 (Fig. 5), the tabs 15 projecting as shown.

The next step is to fold the tabs 15 under or down onto the outer side of the sheet (Fig. 6), whercby'pointed tongues 17 are provided. These tongues are next folded inward over the flaps 16 (Fig. 7). These tongues may be fastened in various ways. For instance the inner faces of the tabs 15 may be coated with an adhesive so that the tabs may be glued to both sides of the orctector at the corners thereof as will be evident from Figs, 7 and 8.

Another manner of fastening is illustrated in Figs. 9 to 11 inclusive wherein the end flaps 16 are provided with slits 18 and the tabs 15 folded and the tongues 1? formed as shown in Fig. 10 and then inserted in the slits 18 as shown in Fig. 11. it will be seen that the tabs 15 being folded down over the outer face of the protector (Fig. 8) and then over the flaps 16 7, will give a plurality of layers or thicknesses of the sheet at the corners, thereby reinforcing the same and adding strength where the hardest wear comes.

It is obvious that the protector is adjustable as it may be placed on books of different sizes and folded accordingly. However to provide for an equal folding of the flaps 16 and to give a greater adjustment. thd protector may be formed in two sections as is shown in Jigs. 12 and 13. Each section has a tongue 20 andthese are overlapped to give the proper width. Une of the tongues 20 has its et 21 glued to the outer faceof the other section, the edge of said other section being covered as is shown in Fig. 13.

This protector permits of many variations and may be made to suit almost any requirement. The reinforced corners are very important and advantageous. This protector owing to its simplicity readily lends itself to economic manufacture.

What 1 claim, is:

1. A book protector having flaps along its top, bottom and outer edges. tabs at each corner of the protector, said flaps being folded inward to inclose the covers of a book, said tabs being folded outward. to reinforce the corners and then folded inward over the flaps and suitably fastened.

2. A book protector having flaps along; its top, bottom and outer edges, the flaps being folded inward over the top bottom and outer edges of the covers of a book, tabs provided at each corner of the pro tector, each tab being folded down against the outer face of the cover so as to provide a projecting tongue, each tongue being folded inward. over the adjacent end flap and secured thereto.

3. A book cover protector sheet having its corners cut off and provided with parallel guide lines for the cutting of slits to provide a reinforcing tab at each corner and top and bottom flaps, an end flap at each side of the sheet adapted to be folded inward on a book cover. tabs being foldahle over the outer and inner faces of the sheet when aplclied to the book to reinforce the corners.

i. A book cover protector sheet having diver ing guide lines at its central portion for the cutting of tongues, the corners of the sheet being cut off and said sheet having guide lines adjacent its cut off corners for the cutting of slits to form reinforcing tabs, said sheet being arranged to'b-e folded to form flaps for inclosing the covers of a book.

in testimony whereof I affix my signature.
